Age: 14 in appearance; around 400 in actuality.
Height: 168 cm / ~ 5'6".
Weight: 54 kg.
Medical Info: Is an owl turned into a human! He's straining to do that, and it's something that he falls out of if he's fighting too hard or injured. I'd assume this is also the reasoning behind why he wears glasses--he can't maintain the normal, perfect eyesight while in human form, and is actually incapable of seeing that well. He CANNOT DIE. Canon is fuzzy on this, but assume he can grow back stuff. It takes a while for things to reform, however, and he will keep and injury and LOOK DEAD for a while. Possibly does need medical attention, but it's not highly necessary. Smaller lacerations and so forth do heal very quickly, but as quickly as say--the Baccano! crew's does.
Eyes: Brown? I think, anyway.
Hair: Whiiiiiiiiiiiiiiiiiiiiiiiite.
Physical traits: Possibly looks like an owl! White hair, pale skin, but otherwise very normal looking!
HOWEVER. He looks different when he fights! Possibly more feral, and given the nature of the fight, he might start to turn back to the form of an owl. He will NOT let it get that far, but his hair will become all feathery. See it in the icon used on this post. Or any of the icons labeled "owl."
What's Okay To Mention Around Him/Her: Nothing past chapter 48, please? I don't want to have to deal with how he would handle his choices there. As it is, I'm fairly certain he comes from around chapter 40, but we'll see. He can handle being told he's fictional, however!
Abilities: He uses a special jutsu that allows him to be a human, so I'd wager that he's pretty strong? IMMORTALITY IS A BIG ONE HERE, personal, never-ending healing, the power to always hit on Raimei at the wrong time, and jutsus. Of course, everything after the first part is limited because a lot of his strength goes toward he first part.
Notes for the Psychics: His thoughts rarely contradict what he's saying! Despite having a mentality of someone over 400 years old, Kouichi surprisingly lives in the moment, and prefers things that way. He loves people, quite a bit actually, and likes to enjoy their presence and come to understand them. Even if he fails sometimes. But this isn't constant! Death is a HUGE mental ping for him, so it will make him think about how he would like to die so he doesn't live a terribly sad and alone life (this ... is actually a paraphrase of actual canon, where he says life would be sad and lonely without the people he cares for). Also, he's a ninja, so he's likely to be thinking ninja-esque thoughts on occasion.
Can I shapeshift/bodyswap/spit at/step on/etc?: Ask, ask, go ahead, go ahead. He's a ninja!
Maim/Murder/Death: Yes, yes, no. The final one is purely because he just. Not able to die.
Cooking: Uh. IDK? MAYBE HE CAN COOK RABBIT, SINCE HE LIKES EATING IT.
